چکیده
With increasing use of dermal fillers, more and more adverse effects are reported. The most devastating one is intravascular injection. We propose a novel needle prototype that allows physicians to prevent intravascular injection.

Novel Double-Needle System That Can Prevent Intravascular Injection of Any Filler
A new type of needle system combines 2 parts, an inner needle and an outer needle. The inner needle is used for filler injection and the outer needle acts as a guiding needle that can observe blood reflow when inserting into the vessel lumen during injection process. This new needle system can be used for all kinds of filler, providing real time monitoring for physician and preventing intravasc...
متن کاملSkin Necrosis with Oculomotor Nerve Palsy Due to a Hyaluronic Acid Filler Injection
Performing rhinoplasty using filler injections, which improve facial wrinkles or soft tissues, is relatively inexpensive. However, intravascular filler injections can cause severe complications, such as skin necrosis and visual loss. We describe a case of blepharoptosis and skin necrosis caused by augmentation rhinoplasty and we discuss the patient's clinical progress. We describe the case of a...
متن کاملComparison of incidence of intravascular injections during transforaminal epidural steroid injection using different needle types
BACKGROUND Infrequent but serious complications of transforaminal epidural steroid injection (TFESI) occur due to inadvertent intravascular injections. A few studies reported that the different needle types can influence on the occurrences of intravascular incidence in TFESI. This study prospectively evaluated whether short-bevel needle can reduce the incidences of intravascular injection of TF...
متن کاملThe Incidence of Intravascular Needle Entrance during Inferior Alveolar Nerve Block Injection
BACKGROUND AND AIMS Dentists administer thousands of local anesthetic injections every day. Injection to a highly vascular area such as pterygomandibular space during an inferior alveolar nerve block has a high risk of intravascular needle entrance. Accidental intravascular injection of local anesthetic agent with vasoconstrictor may result in cardiovascular and central nervous system toxicity,...
متن کاملCT-Fluoroscopic Cervical Transforaminal Epidural Steroid Injections: Extraforaminal Needle Tip Position Decreases Risk of Intravascular Injection.
BACKGROUND AND PURPOSE Cervical transforaminal epidural steroid injections are commonly performed for temporary pain relief or diagnostic presurgical planning in patients with cervical radiculopathy. Intravascular injection of steroids during the procedure can potentially result in cord infarct, stroke, and even death. CT-fluoroscopy allows excellent anatomic resolution and precise needle posit...
